Exercise capacity is limited by environmental heat stress because thermoregulatory systems are altered and cannot prevent the elevation of body temperature due to a complex interplay of physiological, physical, and perceptual alterations. Cooling is an effective strategy to attenuate the temperature rise. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the PEDro scale for assessing methodological quality, we systematically reviewed studies indexed in Medline, Web of Science, EMBASE, Science Direct, Sportdiscus, and Scopus, to evaluate the effects of the cooling vest (CVs) on perceptual response, physiological behavior, and sports performance in adult physical activity practitioners under heat stress conditions. Among the 711 studies identified in the search, 10 studies for the systematic review and eight for the meta-analysis met the inclusion and exclusion criteria. Overall, the use of CVs showed improvements in certain sports performance indicators, being significant ( < 0.05) in test time and substantial in peak power that could be influenced directly by the significant reduction ( < 0.05) in skin temperature and indirectly by the significant improvement ( < 0.05) in thermal and exertional perceptual responses, without the involvement of core temperature. In conclusion, the use of CVs is a cooling technique that influences perceptual response, thermo-physiological behavior, and sports performance. However, further studies are needed to elucidate the relevance of its application to CVs.
运动能力受环境热应激限制，因为体温调节系统发生改变，由于生理、物理和感知变化的复杂相互作用，无法防止体温升高。降温是减轻体温上升的有效策略。根据系统评价和Meta分析的首选报告项目（PRISMA）指南以及评估方法学质量的PEDro量表，我们系统回顾了Medline、科学网、EMBASE、科学Direct、Sportdiscus和Scopus中索引的研究，以评估冷却背心（CVs）对热应激条件下成年体育活动从业者的感知反应、生理行为和运动表现的影响。在搜索中确定的711项研究中，10项用于系统评价，8项用于Meta分析，符合纳入和排除标准。总体而言，使用CVs在某些运动表现指标上有所改善，测试时间显著（<0.05），峰值功率显著提高，这可能直接受到皮肤温度显著降低（<0.05）的影响，间接受到热和运动感知反应显著改善（<0.05）的影响，而与核心温度无关。总之，使用CVs是一种影响感知反应、热生理行为和运动表现的降温技术。然而，需要进一步研究以阐明其在CVs应用中的相关性。
